Why you’ll love this recipe

  • Satisfying quick breakfast – These overnight oats are the perfect breakfast to take on the go during busy mornings. It is so much easier than making a traditional oatmeal recipe each morning.
  • Easy to meal prep – The best part about overnight oats is how easy they are to make! I love to make a big batch. They take almost no prep time, and after a night in the fridge, they are ready to enjoy the next day. This recipe is one of my favorite things to prep on a Sunday night and enjoy the next morning.
  • Customizable – There are endless possibilities to customize your overnight oats! Add nuts, fresh berries, peanut butter, chocolate, anything you would like to make it your own and mix it up.

Serving Suggestions

With 15 grams of protein per serving, these overnight oats are a great high protein meal that can be served on their own. For some extra crunch, I love adding maple cinnamon granola or salted caramel apple granola on top.

My favorite toppings for these peanut butter oats are crunchy roasted peanuts and strawberries. I also like to top them with sliced bananas and creamy peanut butter or cashew butter. Usually I will prep them in small mason jars and add some fresh fruit in the bottom, middle and top like a parfait.

If you would like some extra carbs, I like to pair this with another meal prepped option, like potato cheddar chive bakes. Serve it with some cold brew coffee to complete your breakfast!

If you love these overnight oats, try chocolate cherry chia seed pudding or blueberry coconut chia seed pudding next.

Ingredients

  • Milk – I used almond milk, but coconut milk, oat milk, or any milk of choice will work for this recipe. I also like to use unsweetened vanilla almond milk for a little extra flavor.
  • Plain greek yogurt – you can use any yogurt, but Greek yogurt will help make your overnight oats high protein
  • Peanut butter – you can use salted or unsalted. Just omit the salt if you use salted peanut butter. I like to look for a natural peanut butter because it has the deepest peanut flavor.
  • Maple syrup – the maple syrup is the perfect way to slightly sweeten your overnight oats
  • Rolled oats – rolled oats are best for overnight because they hold their shape while creating the perfect chewy bite.
  • Chia seeds – I love adding chia seeds to overnight oats. They are a great boost in fiber and protein, which are so helpful for satiety
  • Kosher salt – if you use unsalted peanut butter, a bit of kosher salt helps bring out all the flavors in the overnight oats

Ingredient substitutions

These overnight oats recipes are so easy to make in so many different ways! To make it dairy-free, use a non-dairy milk, like soy milk, and dairy-free yogurt. If you go dairy-free, it will also make these overnight oats vegan!

In place of peanut butter, you could do any nut butter. Almond butter would be great. For nut-free, you can omit the peanut butter. If you need this to be gluten-free, be sure to use certified gluten-free oats.

I find that old-fashioned oats are best for this recipe. You can use quick oats for this easy breakfast, but they do break down a bit more. For best results, I do not recommend steel cut oats because they do not soften in the mixture.

There are so many flavor variations that you can make! Top it off with berries like strawberries or raspberries. Bananas are one of my favorites to add. Some chopped nuts like pecans or walnuts are delicious. Chocolate chips would be a great option, especially if you are enjoying this as a dessert. Finish it with a drizzle of honey for extra sweetness.

To make your overnight oats even more high protein, you could mix your milk with whey protein first. I love a vanilla protein powder. If you don’t want to add protein powder but want vanilla flavor, add vanilla extract. You could also add some unflavored collagen powder for extra protein without changing the taste.

How to make

Step 1: Combine Ingredients

Whisk together milk, yogurt, peanut butter and maple syrup. Pour rolled oats and chia seeds into an airtight container.

Pour the wet ingredients into the container with the oat mixture. Mix very, very well.

Step 2: Chill and Enjoy

Place a lid on the container and place in the fridge for at least 8 hours. After soaking, transfer the batch to individual servings in a small mason jar.

Give these creamy peanut butter overnight oats a good stir before serving. Serve with fruit as a topping and some crunchy peanut butter if desired. If the texture and consistency is too thick, you can add an extra splash of almond milk.

Storage and reheating

You can keep these overnight oats in the fridge for up to 5 days. Enjoy chilled right from the refrigerator. If you prefer your oats warmed, you can put them in a microwave safe bowl and microwave until warmed through.

    Hi Madeline I just made my batch tonight and it smells so good I can’t wait to try them! Just one question, if it says 2 jars for the serving would this equate to 2 servings? Just trying to figure that out 🙂 Thank you!
